Belgium's entertainment culture is disproportionate to its size. The Tomorrowland electronic music festival in Boom — annually named the world's best music festival — draws 400,000 visitors over two weekends to a fantasy-stage spectacle that has defined the global electronic music festival format. The Royal Flemish Ballet and the Théâtre Royal de la Monnaie opera house in Brussels are world-class performing institutions. The Ghent Jazz Festival, the Brussels Summer Festival, and the Liège Esperanzah! world music festival extend the entertainment geography across a country where every region has its own distinct cultural calendar. Belgium's comic strip and bande dessinée culture has produced its own specific entertainment circuit — conventions, museum events, and author appearances — that treats comics as a serious performing and visual art.
